Haha, thanks a lot. I'm glad you liked it so much. This was the first time I've used any sort of an upgrade system, I liked it a lot and I'll try to put it into some of my future games.
Thanks for the review.

Awesome Soundboard of Apu! The only thing is that with soundboards im willing to have to download a larger file if the sound quality is better so either if you fix it or make a new one just bump up the quality on the sounds, Good Job!
